My batteries going flat November 15, 2025, 04:02:27 pm [so im new to this. I replaced my 2 lead acid golf vard batteries with the same. But have a problem with the batteries going flat at night and having that annoyingbeep. The thing is im plugged in to a home power 120v also have a solar panel on the roof aswell as the generator but non of them seems to charge/ the batteries. Only way i get a charge in the batteries is with the enjine alternator. Is there a trip switch somewhere? This past summer i did not have the problem it only started after we replaced the batteries. left]
Re: My batteries going flat Reply #1 – November 15, 2025, 05:20:53 pm Welcome to the forum.If the battery is not charging from the converter, when plugged in, or the solar, good chance the hidden circuit breaker has failed. The engione's alternator is connected tothe coach battery through the isolator located under the hood, on the driver's side and downstream from the hidden circuit breaker. Have you checked the converter and solar controller's fuses?Since you have not listed the floor plan or the model year, I can't give you any advice on how to find the circuit breaker. We ask for this information to help us help you. Knowing what part of the country you live in is also helpful.Larry

Re: My batteries going flat Reply #3 – November 17, 2025, 04:08:58 pm Glad it is now fixed.I have no idea why a blown inverter fuse would prevent the coach battery from being charged by the converter or solar.Some inverters are also battery chargers but none of the inverters I have run across in the past few decades have anything do with the solar charging.Larry

Re: My batteries going flat Reply #5 – November 18, 2025, 09:51:54 pm yeah fuse on inverter. Big thing. But after that i was getting a 13.4 v charge in light shade . I find these 12v solar electricity amazing. Got a hut in Africa and it is all run on solar. Fridge ,freezer, water pump and lights. Not one through an inverter just 12v DC. Now I need to find a tulip style wind turbine. Always some wind movement.
